Aureus Mining Inc. ("Aureus" or the "Company")is pleased to provide an update for the early works construction and development program at the New Liberty Gold Project in Liberia ("New Liberty" or the "Project"). The key workstreams are:

·; Marvoe Creek Diversion Channel, measuring 2.6km, has been cleared, with excavation and berm construction to commence in February 2013

·; 20km stretch of laterite road to New Liberty has been regraded

·; Detailed airborne topography survey has been completed

·; Additional housing, office space and maintenance areas currently under construction

Following the completion of the Project's feasibility study, in order to meet the schedule of first gold production in December 2014, the Company's operations team has been focused upon project optimisation studies and the commencement of early works to run alongside the optimisation of the Project's definitive feasibility study.

International Construction and Engineering ("ICE"), an international company with strong experience in Liberia and South Africa, has been appointed to perform the civil and earthworks component of the development of New Liberty.

The following work, critical to the successful development of New Liberty, is currently underway:

·; The Marvoe Creek Diversion Channel has been cleared, with excavation and berm construction to commence in February 2013. Pictures are included on the Company's website via the following links:

About Aureus Mining Inc.

The Company's assets include the New Liberty gold deposit in Liberia (the "New Liberty Gold Project" or the "Project"), which has an estimated proven and probable reserve of 910,000 ounces of gold grading 3.3 g/t and an estimated measured and indicated mineral resource of 1,143,000 ounces of gold grading 3.6 g/t and an estimated inferred mineral resource of 593,000 ounces of gold grading 3.2 g/t. A feasibility study has been completed on the Project and construction has commenced with initial earthworks. The Project is expected to have an eight and a half year mine life and annual production of 120,000 ounces for the first five years of production. The Company has financed the Project's equity funding requirement and is in advanced discussions with interested parties to fund the balance.

The New Liberty Gold Project is located within the Bea Mountain mining licence, which covers 457 km² and has a 25 year, renewable, mineral development agreement. The Bea Mountain mining license also hosts the proximal gold targets of Ndablama, Gondoja and Weaju, which are the focus of exploration programs during 2013. The contiguous Archaen Gold exploration licence, which covers 89 km², is also a focus of exploration for 2013, with Leopard Rock being the main target.

The Company also has gold exploration permits in Cameroon.

Forward-looking Statements 

This press release contains certain forward-looking information. All information, other than information regarding historical fact, that addresses activities, events or developments that Aureus Mining believes, expects or anticipates will or may occur in the future is forward-looking information. Forward-looking information contained in this press release includes, but may not be limited to, the future plans and objectives of Aureus Mining and their anticipated future growth, mineral resource estimates and the anticipated exploration and development activities of Aureus Mining. The foregoing and any other forward-looking information contained in this press release reflects the current expectations, assumptions or beliefs of Aureus Mining based on information currently available to Aureus Mining. With respect to the forward-looking information contained in this press release, Aureus Mining has made assumptions regarding, among other things: general business, economic and mining industry conditions; and it has also been assumed that no material adverse change in the price of precious and/or base metals occurs, no unusual geological or technical problems occur and no significant events occur outside of the normal course of Aureus Mining's respective business.

Such forward-looking information is subject to a number of risks and uncertainties that may cause actual results or events to differ materially from current expectations, including: risks normally incidental to exploration and development of mineral properties; uncertainties in the interpretation of results from drilling and test work; the possibility that future exploration, development or mining results will not be consistent with expectations; uncertainty of mineral resources estimates; adverse changes in precious and/or base metal prices; and future unforeseen liabilities and other factors including, but not limited to, those listed under "Risk Factors" in the Preliminary Prospectus of Aureus Mining Inc. dated April 20, 2011, a copy of which is available on SEDAR at www.sedar.com, and in the Aureus Mining Admission Document, a copy of which is available at www.aureus-mining.com.

Any mineral resource figures referred to in this press release are estimates and no assurances can be given that the indicated levels of minerals will be produced. Such estimates are expressions of judgment based on knowledge, mining experience, analysis of drilling results and industry practices. Valid estimates made at a given time may significantly change when new information becomes available. While Aureus Mining believes that the mineral resource estimates in respect of their respective properties are well established, by their nature mineral resource estimates are imprecise and depend, to a certain extent, upon statistical inferences which may ultimately prove unreliable. If such mineral resource estimates are inaccurate or are reduced in the future, this could have a material adverse impact on Aureus Mining, as applicable. Due to the uncertainty that may be attached to inferred mineral resources, it cannot be assumed that all or any part of an inferred mineral resource will be upgraded to an indicated or measured mineral resource as a result of continued exploration.

Forward-looking information speaks only as of the date on which it is made and, except as may be required by applicable law, Aureus Mining disclaims any obligation to update or modify such forward-looking information, either as a result of new information, future events or for any other reason.
